DROP-BOX LOOM.

Application led October 7, 1924. Serial No. 742,172.

To ZZ ywhom t may Conce/m.'

Be it known that I, JOHN C. SHAMBow, a citizen of the United States,residing at lVoonsocket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Drop-l`loxLooms; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention relates to an imi'novement in drop box looms.

Plain drop box looms were provided with shuttles which had the deliveryeye in the end of the shuttle nearer the selvage when the shuttle wasboxed on the drop box side ot the loom. In this loom the butt of thebobbin was located at the opposite end of the shuttle from the shuttleeye. These looms were satisfactory in operation, but with the advent otthe use ot' t'eelers the weavers attempted to apply the teeler to theloom, inasmuch, however, as the feelers were mounted on the single boxside of the loom and usually made their 'feeling movement in a directionoutward trom the side ol the loom upon which they werey mountedr` such aleeler was not adapted l'or use with the shuttles employed in the loom.Consequently opposite hand shuttles were employed in the looms in orderto adapt them to the use otl the l'eeler mechanism. This, however.although it brought the butt otl the bobbin in the right position forthe teeler, resulted in the maloperation of the drop box, because itthrew the eye. of the shuttle into the shuttle box on the drop box sideot the loom at, the end ot the shuttle remote trom the selvagge with theresult that the yarn Vfrequently was caught between the bindt-r and theshuttle due to the lifting and falling oll the drop box. 'l`he presentinvention contemplates the use in a drop box loom ot the filling teelertype ot a shuttle ha ving` its eye at the same end as the butt of thebobbin and located iu a plane non-registering with the teeler hole otthe shuttle.

The present invention consists in the box loom hereinafter described andparticularly detned in the claims.

In the accompanying drawings Fig. 1 is a diagrammatic view of a plainbox loom embodying the invention: Fig. 2 is a plan,

and Fig. 3 an elevation of a shuttle for the looms.

The illustrated embodiment of the invention is described as follows Thecloth being woven is indicated at 10, the selvages of the cloth areindicated at 11, and the single box 12 is shown at the one side and thedrop box 13 at the other side of the loom. The loom is provided with atilling feeler 14, stopping mechanism 15, and connections therebetween16. A tilling fork 17 is provided, also connected with the stoppingmechanism by the connections 18. The shuttle 20 employed in the leoni isprovided with a feeler hole 21 through which the eeler enters theshuttle and feels of the yarn on the bobbin. When the yarn is exhaustedto a predetermined extent, determined by the operation of the feeler, itstops the loom and the operative places a new bobbin in the shuttle. Theshuttle is provided with a delivery eye 27 which is located in fixedposition at the bobbin butt end of the shuttle, which is the end of theshuttle nearer the selvage when the shuttle is boxed on the drop boxside ot' the loom. The yarn from the bobbin extends from the tip ot' thebobbin through the guide eye 22 into the tension cavity in the end ot'the shuttle where it may be passed through a tension device, it'desired, but which is shown as extending directly t'rom the guide eye 22to the guide eye 23, which leads it from the tension cavity in the endof the shuttle to the top of the shuttle, or to a point near the top ofthe shuttle, where the yarn turns and enters the yarn tube 24 throughwhich the yarn extends to the opposite end ot the shuttle. Here the yarndescends through the guide eye which may be a delivery eye in case thethread is delivered at this point into the groove 2G in the upper partot' the front side ot the shuttle, or the eye 25 may be merely a guideeye, in which case the yarn extends down to the delivery eye 27 near thebottom ot' the shuttle, where it delivers the ya rn to the groove 28 atthe lower front corner of the shuttle.

The position of the delivery eye is important, and is madenon-registering with the position of the feeler hole in the shuttle, sothat when the shuttle is boxed on the filling feeler side of the loomthere is no possibility of the yarn being broken by the blow of thefeeler against it as the teeler enters the shuttle. The filling fork 17on failure ot' the wett indicates absence and operates the stoppingmechanism to stop the loorn.

The shuttle herein described and claiined is particularly adapted foruse in existing box looins provided with lilling teelers because thelocation ot the delivery eye of the shuttle on the side nearer theselvage when il is boxed on the dron box side ot the loom reduces wettbreakage, and the location ot auch eye, in a plane non-registering withthat ot the teeler hole reduces a V'nrther liability ot breakage by theteeler. Obviously the shuttle is ot advantage even in looms un-]'novided with a teeler because of the reduction ot weft breakage due tothe action ot' the binders on the drop box side of the loom.

Having thus described the invention, what is claimed is:

1. A box looin of the tilling teeler type having7 in combination. a layhaving a single box on one end and a drop box on the other end, a'feeler on the single box side ot the loon'i, a stop niotion,connections between the stop Inotion and the feeler, shuttles Yfor theboxes, each provided with a teeler hole and a yarn delivery eye locatedin the end ot the shuttle nearer to the selvage when boxed on the dropbox side of the loom.

Q. A box looin ot the filling` feeler type having. in combination, a layhaving a singlo box on one end and a drop box on the other end, a teeleron the single box side of the loont, a stop inotion.y connectionsbetween the stop inotion and the. lieeler. shuttles for the boxes, eachprovided with a Jf'eeler hole and and a yarn delivery eye in the end otthe shuttle nearer the selvage when the shuttle is boxed in the drop boxside of the loont. said teeler hole and delivery eye being located innon-registeringv planes.

shuttle for teeler loonis having a body provided with a bobbin cavity. ateeler hole in the front et the shuttle. a delivery eye located at thebobbin-butt end ot' the shuttle, and yarn guiding means for eading theyarn troni the bobbin to the delivery eye, said teeler hole and deliveryeye being lo cated in non-registering planes. i

4. A shuttle for Yteeler limnishavinga body provided with a bobbincavitya a tceler hole in the 'front of the shuttle, a delivery eyelocated at the bobbin-butt end of thc shuttle and yarn guiding nieans'tor leading the yarn tron: the bobbin to the. eye.

)t shuttle tor teeler loonis having a body provided with a bobbincavity? a Vtreler hole in the front of the shuttle. a delivery eyelocated at the bobbin-bntt end of the shuttle and jfarn guiding ineensir leading the yarn from the bobbin to the eye. prising a yarn tubeextending alon the bobbin cavity to protect the yam troni contact withthe yarn running oli the bobbin. i

(S. A shuttle for box looms ha\ ing a body provided with a bobbincavity, a delivery eye tired at the bobbin butt end olI the shuttlc, andyarn guiding ineans tor lean/ling the yarn troni the bobbin to the eye.

In testimony whereof l have signed niy naine to this specification.
